  • Log-periodic dipole array antenna and smart skin having the same
    Patent number: 9368874
    Abstract: A log-periodic dipole array antenna according to one exemplary embodiment of the present disclosure includes a dielectric substrate, a radiating element having a plurality of lines extending from a center to an outer side and symmetrically arranged on the dielectric substrate based on the center, so as to resonate in a first frequency band and a second frequency band, the plurality of lines being connected at the center or the outer side of the radiating element in an alternating manner, the lines becoming longer going from up to down of the radiating element fed according to a predetermined log-periodic ratio, and a band stopper formed on one point for connecting the lines to each other.
    Type: Grant
